SULFACETAMIDE SODIUM AND PREDNISOLONE SODIUM PHOSPHATE vs SULSTER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Sulfacetamide sodium inhibits bacterial dihydropteroate synthase, blocking folate synthesis; prednisolone sodium phosphate suppresses inflammation by binding glucocorticoid receptors, inhibiting phospholipase A2 and pro-inflammatory cytokine production.
Sulster is a sulfonamide antibiotic that inhibits bacterial dihydropteroate synthase, blocking folate synthesis and thus bacterial DNA replication.
1-2 drops into the conjunctival sac of the affected eye(s) every 2-4 hours during the day and at bedtime; frequency may be decreased as clinical signs improve.
2.5 mg orally twice daily.

Sulfacetamide: 6-8 hours (prolonged in renal impairment). Prednisolone: 2-4 hours (terminal half-life). Clinically, systemic effects may persist longer due to tissue distribution.
Terminal half-life 3.5-4.5 hours in normal renal function; prolonged to 10-15 hours with creatinine clearance <30 mL/min.
Renal excretion of unchanged sulfacetamide (60-75%) and prednisolone metabolites (primarily conjugated); minimal biliary/fecal elimination (<10% for each).
Primarily renal (60-70% unchanged), with 20-30% as glucuronide conjugate; biliary/fecal <10%.
